[0026] The traction wheel is sleeved on the outer surface of the fixing seat, and then the driving mechanism is started. Next, the adjusting mechanism can be operated through the transmission mechanism, and then each arc-shaped fixing plate 3 can be driven to move and clamp the inner wall of the traction wheel, so that the traction wheel can be fixed.

[0027] In order for the traction sheave to be fixed, Figure 1-2As shown, the adjustment mechanism includes multiple screw rods 4, multiple sleeves 5 and multiple first bevel gears 6, each screw rod 4 is rotatably connected to the inside of the corresponding strip groove, one end of each screw rod 4 passes through the side wall of the corresponding strip groove and extends to the inside of the groove, each first bevel gear 6 is fixedly connected to the rod wall at one end of the corresponding screw rod 4, each sleeve 5 is fixedly sleeved on the rod wall of the corresponding screw rod 4 away from the end of the first bevel gear 6, and each sleeve 5 is fixedly connected to one side of the corresponding arc-shaped fixed plate 3.
